RealVNC – Authentication scheme not supported

[Member berghsg]

Hi All

My new OS: antix 21 64bit
My File Manager: zzzFM
My Desktop environment: IceWM
Theme: Sunnyday-Large
Software Version: VNC-Server-6.10.0-Linux-x64.deb or VNC-Server-6.10.0-Linux-x64-ANY

PROBLEM
If you have been having problems with trying to connect to the RealVNC server that you have recently installed on your OS. And you keep getting the following errors when running the VNC Server gui:
VNC server security settings not configured
Authentication scheme not supported

THE SOLUTION (topic – No Authentication Schemes Configured)
https://help.realvnc.com/hc/en-us/community/posts/5313103951517-No-Authentication-Schemes-Configured

1)
sudo vncpasswd -service
Setting “Password” VNC parameter for Service Mode server
Password:
Verify:
Successfully set “Password” VNC parameter in /root/.vnc/config.d/vncserver-x11

2)
sudo pico /root/.vnc/config.d/vncserver-x11
adding the following to the end of the file
Authentication=VncAuth
Ctrl o
Enter
Ctrl x

3)
sudo /etc/init.d/vncserver-x11-serviced restart

4)
Service should be connectable from a RealVNC reader/viewer (VNC-Viewer-6.22.515-Linux-x64.deb) and in my case it is!

TIPS

i) Check the port vnc server is listening on
sudo netstat -ap | grep vnc
Output:
tcp 0 0 0.0.0.0:5999 0.0.0.0:* LISTEN 6466/vncserver-virt
tcp 0 0 antix2.home:37586 165.254.191.196:https ESTABLISHED 8817/vncserver-x11-
tcp6 0 0 [::]:5999 [::]:* LISTEN 6466/vncserver-virt
udp 0 0 0.0.0.0:5999 0.0.0.0:* 6466/vncserver-virt
udp6 0 0 [::]:5999 [::]:* 6466/vncserver-virt

ii) Set your RealVNC server to startup with boot process
dpkg –list | grep vnc #[will only pick up package installed from VNC-Server-6.10.0-Linux-x64.deb file]
or
apt list | grep vncserver #[will only pick up package installed from VNC-Server-6.10.0-Linux-x64.deb file]
sudo update-rc.d vncserver-x11-serviced defaults

sudo update-rc.d vncserver-virtuald defaults

Restart your PC, RealVNC server should automatically startup with booting
